In order to do proper Amazon SEO on Amazon you have to follow several rules. Old tricks are not working for last several days. I am associated with amazon seo for last 3 years. And regarding wishlist my experience says that you have to do at least 1000 verified fresh wishlist per day for seo. And how many days you have to do this its not sure. Because it depends on your product present conditions and the "keyword" difficulties which you want to rank. But beside this you have to check your product title, description, reviews, social presence, conversation rate and many more.
Thank You!
